John Joseph Murphy (July 14, 1908 – January 14, 1970) was an American All-Star right-handed relief pitcher in Major League Baseball (1932, 1934–1943, 1946–1947) who later became a front office executive in the game.

When his playing days ended, Murphy briefly scouted for the Red Sox, then entered the Boston front office when owner Tom Yawkey appointed him Director of Minor League Operations.

Rising to the position of vice president, Murphy briefly donned a uniform and joined the Mets' coaching staff for the final 11 games of the 1967 campaign during Salty Parker's term as acting manager.

[3] Murphy's promotion to the GM role coincided with the Mets' unveiling of some of the best young pitching talent of the era—including Tom Seaver, Nolan Ryan, Jerry Koosman, Tug McGraw, and others.

Then, with Hodges in command—and with the contributions of Murphy acquisitions Tommie Agee, Donn Clendenon and Al Weis—the 1969 Miracle Mets stunned the baseball community by winning the National League East, sweeping Atlanta in the NLCS, then defeating a heavily favored Baltimore Orioles squad in five World Series games.
